Patented Jan. 1, 1918.

Application filed September 25; 1916. Serial No. 122,057.

To all whom itmay concern:

Be it known that we, MELVILLE E. PETERS, GEORGE H. FA'rr-I, and ALBERT F. MILLER, citizens of the United States of America, residing at the city and county of Denver and State of- Colorado, have invented a new and useful Box-Transferring Mechanism for Boxrapping Machines, of which the following is a specification. f

Our invention relates to a box transferring mechanism; and the objects of our invention are: I

First, to provide means for transferring a box from one position to another position; and

Second, to provide means for moving boxes oneat a time in box wrapping machinery from one predetermined positlon to another predetermined position.

, 'We attain these 'objects'by the mechanism illustrated in the accompanying drawings, in which:

Figure 1 is a vertical, longitudinal sectional view of a portion of a box covering machine, showing the improved box transferring mechanism. And

Fig. 2 is a longitudinal sectional view through the transferring mechanism.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings,

The numeral 1 designates a cylindrical tube having closed ends. This tube is clamped in a split hub 2 that is formed on a vertically projecting bracket 3 that is secured to the end of the table portion of a frame 4. This outer tube is provided with an air inlet nipple 5 at its rear end, and with vent apertures 6 at its front end portion. This tube is also provided with a cushionin washer 7 that lies a ainst its 23 8 front head. WVithin this outer tube a second tubular member 8 is slidably mounted, which projects through the front head 9 of the outer tube. The outer end of the inner tube 8 is closed by a head end portion 10 while its inner end is open to the air inlet of the outer tube. l/Vithin this inner tube a piston head 11 is slidably mounted, and a plunger rod 12 is secured to the piston head. The

outer end of this plungerrod is provided with a disk 13 that strikes the end of the box when the plunger is thrown out by the air pressure. When air is forced into the outer tube from'an air cylinder 14, which is secured .to the bed plate of the frame 1, through a pipe-15, which connects thepump and the nipple 5, the inner tube 8 and the plunger head and rod are shot out to the end of their full-lengths, which is sufficient to enable the plunger to engage a box'and move it against astop not shown at the end The suction stroke of'the piston'drawslthe plunger back.

Our invention provides a simple, practical and reliable box transferring mechanism, that can be adapted to move boxes under various conditions and that can be applied to different machines that are engaged in box making work, a practical example of the practical use of our invention being illustrated in our pending application for a patent for a multiple stage treatment box wrapping machine, filed November 5, 1915, Serial Number 59,860, and, while we have illustrated and described the preferred construction and arrangement of our invention, we do not wish to be limited to it, as many changes might be made without departing from the spirit of our invention.

Having described our invention, what We claim as new and desire to secure by Letters Patent, is:

1. In a box transfer mechanism, the combination with a supporting frame, and a power actuated shaft in said frame provided witha cam, of a pneumatically operated plunger in a cylinder, an air cylinder and piston, a pipe connecting said cylinders, and a'lever operated by said cam for reciprocating said piston.

2. In a box transferring mechanism, the

combination with a frame, a power driven shaft mounted therein, a cam on said shaft,

an air cylinder and piston in said frame, and a lever actuated by said cam for operating said piston, of a tubular housing sup;

ported on said frame, a pipe connecting said housing and said cylinder, and an air actuated plunger slidably mounted in said housing.

3. In a box transferring mechanism, the combination with a frame, a power driven shaft mounted therein, a cam on said shaft, an air cylinder and piston in said frame, and a lever actuated by said cam for operating said piston, of a tubular housing rigidly mounted on said frame, a pipe connecting said cylinder and said housing, a tubular member telescopically mounted in said housing having its rear end open, and a rod telescopically mounted in said tubular member,

having an abutment head on its outer end.

4. In a box transferring mechanism, the combination with a frame, a power driven shaft mounted therein, a cam on said shaft, an air cylinder and piston in said frame, means including a lever arranged to be actuated by said cam for operating said piston, a two-part telescopically connected cylindrical tubularhousing supported on said frame, a pipe connecting said housing and said cylinder, and an air actuated plunger slidably mounted in said housing, said plunger being arranged to be forced out by the air pressure of said cylinders to trans- Gopies of this patent may be obtained for mit abox and to draw back said plunger by suction.

5. In a box transferringmechanism, the combination with a frame, a power driven shaft mounted therein, a cam on said shaft, an air cylinder in said frame, provided with a reciprocating piston, a lever pivotally connected at one end to said piston and operated by said cam, of a tubular housing rigidly mounted on said frame, a pipe connecting said cylinder and said housing, a tubular member telescopically mounted in said housing having its rear end open, and a rod telescopically mounted in said tubular member, having an abutment head on its outer end, said plunger being arranged to be forced out by said cylinders air pressure to transmit a box, and sald plunger being arranged to be drawn back on the suction stroke of said piston by suction.

In testimony whereof We affix our signatures in presence of two witnesses.
